<P CLASS=para>
<tt CLASS=literal>MenuContainer</tt> is an interface 
implemented by the three menu containers: <tt CLASS=literal>Frame</tt>, 
<tt CLASS=literal>Menu</tt>, and <tt CLASS=literal>MenuBar</tt>; 
Java 1.1 adds a fourth, <tt CLASS=literal>Component</tt>. 
You should never need to worry about the interface since it does all its 
work behind the scenes for you. You will notice that the interface 
does not define an <tt CLASS=literal>add()</tt> method. 
Each type of <tt CLASS=literal>MenuContainer</tt> 
defines its own <tt CLASS=literal>add()</tt> method 
to add menus to itself.

<DD>

<P CLASS=para>
The <tt CLASS=literal>getFont()</tt> method should 
provide an object's font. <tt CLASS=literal>MenuItem</tt> 
implements this method, so all of its subclasses inherit it. <tt CLASS=literal>MenuBar</tt> 
implements it, too, while <tt CLASS=literal>Frame</tt> 
gets the method from <tt CLASS=literal>Component</tt>. 

<p>
<DT CLASS=varlistentry><I CLASS=emphasis>public abstract boolean postEvent (Event e) <img src="gifs/wstar.gif" alt="(Deprecated)" border=0></I><br>
<DD>

<P CLASS=para>
The <tt CLASS=literal>postEvent()</tt> method should 
post <tt CLASS=literal>Event</tt> <tt CLASS=literal>e</tt> 
to the object. <tt CLASS=literal>MenuComponent</tt> 
implements this method, so all of its subclasses inherit it. (<tt CLASS=literal>Frame</tt> 
gets the method from <tt CLASS=literal>Component</tt>.) 

<p>
<DT CLASS=varlistentry><I CLASS=emphasis>public abstract void remove (MenuComponent component) </I><br>
<DD>

<P CLASS=para>
The <tt CLASS=literal>remove()</tt> method should 
remove the <tt CLASS=literal>MenuComponent</tt> <tt CLASS=literal>component</tt> 
from the object. If <tt CLASS=literal>component</tt> 
was not contained within the object, nothing should happen. </DL>
